£54.39
The ABB S301P-K32 (2CDS381001R0537) is a premium single-pole miniature circuit breaker (MCB) engineered to protect industrial electrical installations against overloads and short circuits. Part of the renowned ABB S300P series, it offers a high 25 kA breaking capacity, making it ideal for demanding industrial environments where dependable circuit protection is essential.
The K tripping characteristic is specifically designed for circuits supplying motors, transformers, solenoids and other inductive loads that experience high inrush currents. This helps minimise nuisance tripping during start-up while ensuring rapid disconnection during genuine fault conditions.
With a 32 A rated current, compact DIN rail mounting and ABB's proven reliability, the S301P-K32 is an excellent choice for industrial control panels, OEM machinery, manufacturing equipment and commercial electrical distribution systems.
Miniature circuit breakers are essential safety devices that automatically disconnect electrical circuits when overloads or short circuits occur. Unlike conventional fuses, they can simply be reset after the fault has been rectified, reducing downtime and maintenance costs.
The ABB S301P-K32 has been developed specifically for industrial installations where motors, transformers and inductive equipment generate high inrush currents. Its K characteristic provides dependable protection without unnecessary tripping, helping maximise system availability.
